Objective Cortisol-producing adenoma (CPA) is a major subtype of functional adrenal tumors. CPAs are generally treated with adrenalectomy; however, it is difficult to predict the ideal duration of glucocorticoid replacement after resection. This study explored pre-operative factors predictive of glucocorticoid replacement therapy duration after CPA resection.

Article Synopsis
  • Hospital-acquired bloodstream infections (HA-BSI) in ICU patients can be life-threatening, and this study aimed to see how early adequate antibiotic treatment affects 28-day mortality rates for patients who survive at least one day after infection onset.
  • Using data from a multicenter study with 2,418 patients, researchers found that those who received adequate treatment within 24 hours had a lower 28-day mortality rate (32.8%) compared to those who were inadequately treated (40%).
  • The study concluded that inadequate antibiotic therapy within 24 hours contributes significantly to 28-day mortality, indicating that quicker treatment could greatly improve patient outcomes in cases of HA-BSI.

Purpose: To investigate the anatomical changes and surgical outcomes of hemi-temporal internal limiting membrane (ILM) peeling and conventional ILM peeling for idiopathic macular hole (MH).

Methods: This randomized controlled trial was conducted at 3 centers and included 50 participants with MHs of <400 µm in minimum diameter for a duration of <6 months. All participants had undergone vitrectomy with either hemi-temporal ILM peeling (Hemi group) or 360° ILM peeling (360° group) with an injection of 5% sulfur hexafluoride gas, with or without simultaneous cataract surgery, from July 2017 to January 2021.

Article Synopsis
  • - This study evaluates how common unilateral hyperaldosteronism (UHA) is among patients with primary aldosteronism (PA) and examines its clinical features, using data from 199 PA patients in Japan.
  • - The research categorizes the patients into confirmed PA, where over half have UHA, and borderline PA, with about 15-20% having UHA; hypokalemia is identified as a significant predictor for UHA in borderline cases.
  • - The findings highlight the crucial role of adrenal venous sampling in confirmed PA cases and emphasize the importance of thorough testing and considering multiple clinical indicators for assessing borderline PA cases.

Aldosterone secretion in primary aldosteronism (PA) is often regulated by adrenocorticotropic hormone (ACTH) in addition to its autonomous secretion. However, the clinical characteristics and risk of cardiovascular and cerebrovascular (CCV) events in PA patients with aldosterone responsiveness to ACTH stimulation remain unclear. This study aimed to investigate the prevalence of CCV events in PA patients with high aldosterone responsiveness to ACTH stimulation.

Background: High shock impedance is associated with conversion failure among patients with subcutaneous implantable cardioverter defibrillators (S-ICD). Currently, there is no preoperative assessment method for predicting high shock impedance. This study examined the efficacy of chest computed tomography (CT) as a preoperative evaluation tool to assess the shock impedance of S-ICDs.

There are no clear criteria for selecting elderly patients with hematologic malignancies eligible for allogeneic hematopoietic stem cell transplantation (HSCT). This study aimed to evaluate inflammatory and nutritional status biomarkers as prognostic indicators of allogeneic HSCT in elderly patients. We compared the prognostic effects of 4 representative pretransplantation biomarkers: C-reactive protein-to-albumin ratio (CAR), Glasgow Prognostic Score (GPS), prognostic nutritional index (PNI), and albumin-to-globulin ratio (AGR).

Background: This study evaluated the non-inferiority of dexamethasone (DEX) on day 1, with sparing on days 2-4 in cisplatin-based chemotherapy.

Methods: Patients with malignant solid tumors who were treated with cisplatin (≥50 mg/m²) were randomly assigned (1:1) to receive either DEX on days 1-4 (Arm D4) or DEX on day 1 (Arm D1) plus palonosetron, NK-1 RA, and olanzapine (5 mg). The primary endpoint was complete response (CR) during the delayed (24-120 h) phase.

Background: Bronchial hyperresponsiveness testing is useful for diagnosing and predicting the risk of bronchial asthma attacks. The Astograph is a tidal breathing method often used in as bronchial provocation testing in Japan. The minimum methachorine dose (Dmin) indicates bronchial sensitivity and is used mainly as an index of bronchial hyperresponsiveness.

  • This observational study evaluated the outcomes of peritoneal dialysis (PD) catheter placement in Japan to see if they align with the International Society for Peritoneal Dialysis guidelines.
  • The study tracked 409 adult patients who underwent PD catheter placement, finding a low rate of catheter patency failure (6.2%) and a technique failure rate of 15.3% after 12 months.
  • Factors influencing technique failure included lower serum albumin levels and type of catheter used, while diabetes increased the risk of perioperative infections; however, overall complications met ISPD audit standards.

  • Overactivation of the renin-angiotensin system (RAS) could lead to worse outcomes for COVID-19 patients, prompting a study to see if ACE inhibitors or ARBs could help.
  • In a clinical trial with 721 patients, participants were randomly assigned to receive either an ACE inhibitor, an ARB, or no RAS inhibitor to evaluate their effects on patient recovery.
  • Results showed no significant improvement in organ support-free days among the treatment groups compared to the control, leading to the discontinuation of enrollment due to safety concerns.

Background: Omalizumab, an anti-IgE antibody, has clinical efficacy against respiratory symptoms of aspirin-exacerbated respiratory disease (AERD). However, some patients with AERD also present with extrarespiratory (chest, gastrointestinal, and/or cutaneous) symptoms, which are resistant to conventional treatment but can be alleviated by systemic corticosteroids.

Objective: We evaluated the efficacy of omalizumab on extrarespiratory symptoms related to AERD.

Article Synopsis
  • The study developed a machine-learning algorithm to help diagnose aldosterone-producing adenoma (APA) using a comprehensive dataset from Japan, involving 41 healthcare centers and patients treated between 2006 and 2019.
  • An ensemble-learning model (ELM) was created by combining seven machine-learning programs, focusing on key predictive factors like serum potassium and aldosterone levels, achieving an impressive accuracy with AUC values of 0.899 for screening and 0.913 for confirmatory tests.
  • This algorithm aims to enhance APA diagnosis in primary care settings, ensuring patients with potentially treatable conditions are accurately identified and managed.
